ENDLES-S-APRON COMPRESSOR AND DISIN'IEGRATOR.

Application filed November 26, 1915, Serial No. 63,436. Renewed March 28, 1917.

To all whom it may concern:

Be it known that I, Janus A. ANminsoN, a citizen of the United States, resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Endless- Apron Compressors and Disintegrators, of which the following is a specification.

The main object of this invention is to provide a disintegrator and compressor formed of endless aprons between which the material is compressed and disintegrated.

Another object of the invention is to provide novel and improved compressing and disintegrating apron wherein the links are interlocked throughout their transverse edges and the use of pivot pins is avoided.

Another object of the invention is to provide a disintegrating endless apron formed of transversely extending interlocked links having disintegrator bars between the lin rs, said bars extending transversely across the aprons and projecting beyond the ope ative surface thereof.

Another object of the invention is to provide two endless conveying and disintegrating aprons having their operating surfaces opposed, each of said aprons being provided with transversely extending disintegrating bars, and driving one of said aprons at a higher speed than the other, whereby the material between the aprons will be compressed and disintegrated as the disintegrator bars on the more rapidly moving apron approach and pass the disintegrating bars on the slower moving apron.

There are other important objects and advantages of the invention resulting from the specific construction of the aprons, all of which will be more fully hereinafter described.

The apparatus shown in the drawings and described herein is primarily adapted for compressing and disintegrating garbage, but the invention is adapted for other uses, and of course, I am not to be limited as to the application or use of the invention.

In the drawing, Figure 1 is a vertical sectional view of the disintegrator and compressor;

Fig. 2 a plan view thereof;

Referring to the various parts by numerals, 1 designates the supporting frame between which the aprons accurately fit, said frame forming a means for retaining on the aprons the material to be crushed and disintegrated. The lower apron 2, upon which the material to be crushed is delivered through a spout or chute 3, is mounted on broad drums 4i, 5 and 6. The drums 5 and 6 are mounted in rigid bearings which are horizontally in line, while the drum t is mounted in a horizontally adjustable bearing 7. The object of providing an adjustable bearing for the drum 4 is to provide means for taking up any slack in the apron due to the wear or stretching of the parts. The upper apron 8 is mounted on drums 9, 10 and 11. The bearings of the drums 9 and 10 are vertically over the bearings of the drums 6 and 5 respectively; and said bearings for the drums 9 and 10 are mounted in vertically movable boxes 12, said boxes being held in their lowermost position by means of strong springs 13. By this means the drums 9 and 10 will be capable of a vertical movement to permit of the separation of the aprons should any uncrushable material be delivered between them. The pressure of the springs 13 may be adjusted by means of screws 1% and suitable followers bearing upon said springs. The drum 11 is mounted in the forward part of the machine frame above the drum 10 in order that the lower run of the apron 8 will incline upwardly and forwardly to provide a wide mouth between the two aprons into which the material may be delivered from the spout 3. The journal boxes 15 of the drum 11 is horizontally adjustable in order to take up any slack in the apron 8 due to the wear of the parts or stretching thereof. The lower run of the apron 8 between drums 9 and 10 is close to the upper surface of the upper run of the apron 2, so that the material placed between the aprons will be crushed and disintegrated between said portions of the aprons. The aprons are driven by any suitable gearing in the direction indicated by the arrows in Fig. 1 so that the material delivered between the forward portions thereof will be gradually crushed and disintegrated as the aprons approach each other, and will be still further crushed and disintegrated between the disintegrator bars as the bars on the upper apron approach and pass the disintegrator bars on the lower apron. The gearing operating the upper apron will drive said apron at a much higher speed than the lower apron is driven in order to secure the final crushing and disintegrating action of the disintegrator bars.

Each of the compressing and disintegrating aprons is formed of a series of flat links 16 and 17, said links extending entirely across the apron. The links 16 form the outer compressing surface of the apron, while the links 17 form the inner surface thereof. The links 16 are formed at their transverse edges with inwardly turned hooks 18; and the links 17 are formed with outwardly turned hooks 19 along their transverse edges. The hooks 18 and 19 are interlocked so that the apron is formed by an endless chain of said links hooked together along their transverse edges. The links 17 are adapted to engage the drums, and said drums are formed with longitudinally extending ribs 20 which fit in between the hooks 19 of the adjoining links 17, in the manner of a sprocket wheel or drum. The links 17 bear on the drums between the ribs 20, as shown clearly in Fig. 1. The links may be moved transversely in order to bring the hooks 18 and 19 into engagement with ach other or to separate them for the purpose of dismantling and disconnecting the aprons. The aprons fit closely between the sides of the frame 1, so that said frame serves as a means to hold the links inengagement with each other and to prevent any lateral shifting movement. Between the hooks 18 of adjoining links 16 are arranged transversely extending disintegrating bars 21. These bars serve the double purpose of spacing the links 16 and holding the hooks 18 in engagement with the hooks 19, and also as disintegrating bars. The outer surfaces of these bars are convex and project slightly beyond the operating faces or surfaces of the links 16. These bars may be placed in position between the links 17 by sliding them in transversely of the apron, and when in position the sides of the supporting frame prevent lateral movement of them. The side frames, or one of them, may be provided. with a suitable aperture through which the links and the disintegrator bars may be moved when connecting up or disconnecting the aprons. Plates 25 close said apertures.

As shown in Fig. 1, those portions of the pressing and disintegrating aprons which run between the rolls 5 and 6, and 9 and 10, are close together and the convex surfaces of the disintegrator bars practically engage each other as the bars on the more rapidly moving upper apron pass the bars on the slower moving lower apron. The result of this is that the material between the surfaces of said aprons is squeezed and disintegrated between said bars. The liquids, water and liquid fats and the like, are squeezed out of the material and pass down through the aprons, While the squeezed and disintegrated material is delivered at the rear of the machine. Those portions of the disintegrator aprons running between the rolls 5 and 6, and 9 and 10, are held in place by means of guides 22 and 23 secured to the inner sides of the machine frame. The upper guide or track 23 is yieldingly held in place by springs 24:, said springs being adjustable by means of screws 26. It is obvious that the guide 23 must yield in a manner similar to the upper drums 9 and 10, to permit of the passage of any material which cannot be crushed between the aprons. By this means a more thorough disintegration of the material will be obtained as the disintegrator bars pass each other.

From the foregoing it is manifest that I provide a disintegrator consisting of an upper and a lower broad, flat conveying and disintegrating apron, between which aprons garbage will be completely compressed and disintegrated. The upper apron is yieldably mounted in order that the aprons may separate and permit of the passage of uncrushable material such as cobble stones, pieces of iron, and the like, which frequently find their way into garbage.

It is also manifest that the disintegrator bars may be removed at will without disconnecting the apron links. This facilitates the removal of worn bars and the replacing of new ones. It is also of great advantage to form the links 16 and 17 of the same size in order that they may be readily interchanged to form either the outer or the inner surface of the apron. By this means it will be necessary to form only one size and shape of link, thus simplifying manufacture and the assembling and repair of the disintegrator aprons. By means of the adjustable bearings for rolls 9 and 10, the space between the parallel runs of the aprons may be varied in order to vary the degree of compression and disintegration of the garbage or other material fed between the aprons. It will, of course, be understood that any suitable form of disintegrator bars may be employed; and that provision may be made for the ready escape of compressed liquid from between the disintegrator aprons.
